26 Claims-i (Cl. 194.-51)

The vpresent invention relates to check-controlled lock mechanisms and, more particularly-"to mechanisms adapted for association with lockers and other similarstorage compartments. My present invention further relates to locking mechanisms of the above type wherein a customer after depositing 'a coin or other check will obtain a key and, thereby, have use of the corresponding compartment or locker for storage purposes, and yet an attendant having a master key mayhave access to the compartment, the lock mechanism and-the check receiving. receptacles.

In addition, my present invention is' similar to and is used for substantially the same purposeas disclosed in my application for Check-Controlled Lock Mechanism, SerialNo'. 247,319; filed September 21; 1951..

An object of this invention is to provide a check-controlled lock mechanism which is of such design that it readily can be adapted" for operation by coins-or other checks of varoius sizes.

Another, object of the invention is the provision in a check-controlled. mechanism of the' above mentioned type of a means for detecting and rejecting checks-not having the predetermined characteristics of size required-to effect operation of the mechanism;

An additional object of my invention-isto provide a check-controlled mechanism of the-above'mentioned type wherein an attendant'may' have access to thesame without depositing a normally required check.

A still further object of myinvention is to provide a check-controlled, easily removable lock'mechanism which is relatively. simplein structure, yet durable in use and comparatively inexpensive to manufacture;

Another object of the invention is to provide a lock mechanism which'readily can be'applied'to and removedfrom a locker door by an authdrizedattendant:

FIGURES 1 TO 7.PREFERRED EMBODIMENT Referring more particularly to the' drawings, Figure l shows a plurality of locker compartments 20; onlyone of which is fully illustrated, and although conventionally. the lockers are arranged in series it'will be' appreciated that they may be individually employedj Each of the locker compartments 20"includes'a pivoted door or'closure 22, having on itsinner surface a removably'mounted check-controlledlock niechanisiri 24' of my' pre sent inven-' tion; it being understood that the closure 22 is'provi'ded with suitable apertures 26, 28 and 30"t'o provide 'accessto the various manually controlled lock actutaingfele'ments carried by my lock mechanism 24.

A base plate 32 of boX-like'form carries-the m'echanism and is provided with a cover 33, mounted on a hinge, indicated by numeral 35, and held" in closed position by a latch 37. The operation of the latch 37' is effected by an attendant having a master keyin a manner subsequently described. For removably mounting "the mechanism 24 to the compartment door 22 the base plate 32is provided with apertures 34fadapted'to registerwith threaded stud elements 36 welded or otherwise secured to the rear face of the compartment door'22 as indicatedat 38. The base plate 32 obviouslymay be securely fastened to the door 22 by means of taps or nuts 40 threaded on the studs 36.

The mechanism 24 includes a lock barrel 42 of known type rotatably mounted on'th'e base plate 32 for-movement through a are by means ofa customerskey. 44, shown in Figures 4 and 7, and adapted to be rotated through a second 90 are by means of master 'key (not shown). The customers key is retained by the lock barrel in all positions thereof, except one, the'locking position in which the key may be withdrawn from the barrel 42 and retained by the customer.

Check-handling mechanism" As indicated in the drawing Figures l5, a check slot 46 is associated With'a check chute 48 having a graduatedaperture 50 in a side wall portion thereof for the purpose of providing an ejecting path for checksor objects which are not of the predetermined denomination and size for which the lock mechanism is designedto be -responsive.

A check-size detector and rejection mechanismasso releasing mechanism and includes a selector detent 52 pivotally mounted on a horizontal pin 54 and having a curved end portion 56 extending into the check chute 48. The opposite end of the detent is provided with a weighted portion 58 having a laterally extending flange 60 normally positioned between a latch bar 62 of the lock barrel releasing mechanism and the base plate 32.

Normally this curved end portion 56 extends within the chute 48 through an aperture 51 as shown in the full line position indicated in Figure 2. When a check of the required size is deposited within the chute the portion 56 of the detent 52 is depressed and held in the dotted line position as viewed in this figure, the check being too large to be rejected through the graduated aperture 50. It will be understood that this aperture 50 and the sidewall of the chute 48, adjacent the check platform 68 of the latch bar 62, will be of such dimension as to prevent checks of the proper size or denomination from being rejected. However, checks of smaller size or denomination will only momentarily trigger the selector detent 52 and then fall onto the curved end portion 56 of the check platform 68 to be rejected through the graduated aperture 50. As the small checks or objects roll through the aperture, which is too small to pass checks of the required size, they will fall downwardly by gravity into a check box or be returned to the operator through a suitable opening as desired. The rejected check receptacle and return opening have not been shown as they are conventional in check handling apparatus and their function will be readily perceived by those skilled in this art.

It readily will be apparent that checks or other objects larger than the correct size cannot be inserted into the check slot 46 or chute 48, therefore, such checks will present no problem. It will also be understood that the dimensions of the check slot 46 and chute 48 are larger than the dimensions of the proper check by only a very slight amount so as to allow the checks to pass freely therethrough and yet present no difficulty to the operation of the device when the check operates the selector detent 52 and comes to rest on the platform 68.

Manually operated lock barrel releasing mechanism This lock barrel releasing mechanism includes a latch bar 62 pivotally mounted for horizontal swinging movement about a pin 64 carried by a wall bracket 66 on the base plate 32. One end of this latch bar 62 is provided with a downwardly inclined check receiving platform 68 normally extending within the chute 48 through the aperture 70. The opposite end 63 of the latch bar 62 is secured to one end of shaft 72, manually operated by a knob 74 secured to the outer end thereof. This shaft 72 passes through an opening 76 in the base plate 32 of the lock mechanism 24 and a second opening 28 in the front wall of the storage compartment closure 22, as clearly shown in Figures 4, and 6. The latch bar 62 is normally retained in inoperative position by a wire type compression spring 80, disposed about the same between the inner surface of the base plate 32 and the end 63 of the latch bar 62 secured to the shaft.

Should a check of the required size be inserted into the check slot the end of the selector detent which is partially disposed within the chute will be moved to and be held in position by the weight of the check, as shown in Figure 2. In this position of the selector detent 52 the latch bar 62 may be pivoted by means of the knob 74 to remove the check platform 68 from the chute 48, allowing the check to fall into a suitable receptacle and simultaneously to release the lock barrel 42 in a manner described hereinafter.

As best shown in Figures 2, 4 and 7, the lock barrel 42 18 provided with a locking bolt 82, which is rigidly secured thereto and extends radially and outwardly thereof. This locking bolt 82 serves three purposes. First, it etfects the necessary locking of the compartment closure when the lock barrel 42 is rotated into the position shown in Figure 2, wherein the bolt 82 is horizontally disposed and at which point the customers key may be withdrawn from the barrel 42. Secondly, the bolt 82 and lock barrel 42 is held against rotation in the key-retaining unlocked position wherein the locking bolt 82 projects vertically upward, engaging certain elements of the manually operated key-releasing mechanism as discussed below. Thirdly, the locking bolt 82, under the influence of a master key, may be rotated partially through an additional 90 arc to unlock the compartment closure and upon further rotation through said arc to actuate a detent 84, holding the cover 33 of the mechanism 24 in closed position.

In holding the lock barrel 42 against rotation when in its key-retaining unlock position, a holding bar 86 is provided, positioned above and extending over the lock barrel 42, as shown in Figures 2, 4 and 6. This holding bar 86 is pivotally mounted on the inner face of the base plate 32 as indicated at 88 for pivotal movement in a vertical plane, the pivotal movement of the bar being limited in the horizontal position by a pin 89 and in the elevated position by a spring 90, carried by the inner end 92 of the bar 86, and coacting with a horizontally disposed pin 94.

The holding bar 86 is provided with a vertical, longitudinally extending slot 96, indicated in Figure 2, adapted to receive the locking bolt 82 for locking engagement therewith when the lock barrel 42 is in its key-retaining unlocked position. It will be understood that while lock barrel 42 and holding bar 86 are in engagement, the lock barrel 42 cannot be rotated from its key-retaining unlocked position, however, upon the presence of a proper check freeing the latch bar 62 the manually operated mechanism described below operates the holding bar 86 to the elevated position releasing the bolt 82.

For effecting pivotal movement of the bolt holding bar 86 upwardly about its mounting 88, a vertically disposed camming member 98, pivoted about the pin 100, in turn carried by the bracket 102 on the base plate 32, is provided. The upper portion 106 of camming member 98 cooperates with a cam surface 104 formed on the lower edge surface of the bolt holding bar 86, as shown in Figures 5 and 6, and it will be appreciated that by this relationship, as the camming member is operated by the knob shaft 72, through a resilient connection 108, the upper extremity 106 of the camming member 98 will be swung to the left, as viewed in Figures 5 and 6, moving the bolt holding bar 86 in a counterclockwise direction. Thus, it will beapparent the knob shaft 72 cannot be operated to efiect movement of the camming member 98 elevating the bolt holding bar 86 and disengaging the slot 96 from the bolt 82 unless the selector detent 52 has first been moved to the dotted line position, as shown in Figure l, by the presence of a check of the proper size or denomination.

A holding detent 112 pivotally carried by the bracket 114 on the rear face of the base plate 32 is adapted to engage the camming member 98 as the shaft 72 is pulled outwardly by the operator for momentarily holding the camming member 98 in position, maintaining the bolt holding bar 86 elevated, freeing the bolt 82 from its keyretaining unlock position so that it may be moved to its key-releasing lock position.

The outer extremity 83 of the bolt 82 is arcuately I shaped or rounded off, providing clearance and permitting the lock barrel 42 to be rotated by the customers key 44 to a position where the bolt 82 projects horizontally outwardly for engagement with the lock keeper 108 of the compartment 20, as illustrated in Figure 1.

A radially projecting cam element 110, fixed to the inner end of the lock barrel is angularly disposed with respect to the bolt 82 and is adapted to engage a holding detent 112, upon rotation of the lock barrel 42, to free the camming member 98 from its operative or bolt holding bar engaging position.

As shown in Figures 3, 4, 5, 6 and 7, the lock-controlling elements. are-1 {positioned within a cover :member33, ap'ertureda-t 116 for accommodating the bolt 82 during its docking and unlocldngwnovement, the: cover being the latch detent 37 whereby the same is moved to position freeing the same from thekeeper-M carried' by the casing 33. Thus, from time to time the attendant may have access to the compartment 20, interior of the lock mechanism 24 and the coin or check receiving receptacle or receptacles.

' Check size ton-version unit In various installations it may be desirable to have a lock mechanism responsive to checks of larger sizes or denominations, therefore, the check slot 46 and chute 43 may be modified as shown in Figures 1, 2 and 3. in these viet '3, my lock mechanism is arranged by means of a check slot insert 126 and a removable chute partition or strip 134 to be responsive to checkscf a small size or denomination. The partition or strip 134 extends only 'partially across the aperture'50 forming an opening to pass objects or checks of insufiicient size and to arrest n checks of the proper size or denomination.

To adapt the mechanism for response to larger checks the insert 126 may be removed from the check slot 46 and the partition 134 withdrawn from the chute wherevby'the side walls defining the chute-will be 130 and.1 36, f:

registering with the cylindrical opening formed in the I employ a substantially U-shaped spring steel wrench 138, as shown in Figure 3, to remove the insert 126 from the check slot 46. This Wrench 138 may be deformed for i; insertion through the bore of the insert 126 and will then open outwardly whereby lateral projections 140will engage the inner end of the insert 126 for its removal.

'The removable wall partition 134 Within the check chute 48 is retained in position by a pin 142 passing through the rear wall 144 of the chute 48, an aperture 146 in the removable partition and threadablyreceived in anaperture 148 in the base'plate 32. When the pin :is removed the partition 134 may be withdrawn by hand,

"and to facilitate this operation a laterally projecting pin 150 is provided at the uper extremity-of the-same.

The operation of the selector detent 52 within the lower portion of the check chute 48, responsive to proper checks to trigger the lock-releasing mechanism into the dotted line position, will be obvious in view of the operation of the detent 52 by checks, asdescribed above.=

- Obviously, partitions or slides 134 of varying sizes may be-used with my check chute, adapting the same and the aperture 50 for use with checks of varying sizes.

Operation It is thought with the foregoing description the mode of operation of the present lock mechanism is apparent. Briefly, if it is desired touse the locker compartment for the storage of clothes or other articles, the customer simply places the articles within an open compartment and then deposits a check of the proper denomination inthe check slot 46 and chute 48. The deposited check drops through chute 48 depressing the selector detent-52 and comes to rest on the coin platform 68 of the latch bar 62 to permit the latter to be pivoted by means of i the knob 74 and connected shaft 72 to free the check,

and, in addition, through the resilient coupling 121 to move the camming member98 into position elevating "the bolt holding bar 86 to freethe bolt 82 of the lock barrel 42. Thus -lock' barrel-42 may-be turned-through 183. with a cam surface 180 formed on the lower edge surface -of a bolt holding bar 173, as shown in Figure 10, andthe atb'acnrs the 490 arc tothe key releasing"locked'vposition, illustr'ated in vfull .lines' in Figure -2. 'P'At-thiS time the -eus- .tc'mers key '44-may-be withdrawn from the lock bar'rel 42 to be retained. by him until access to the lock barrel is again desired. During this interval, the lock barrel 42, by means of a masterkey may be again rotated through a further arc" in a clo'ckwis'e directionyas viewed in Figure 2, permitting an attendant to have access to the compartment and to the lock mechanism and check receptacles in themanner described above.

Subsequently, the customer may again have-access to the tlocker by the use of his key 44 by "moving thebolt 82 back through the first 90 arc to the 'customers key returning unlock'position, wherein the bolt '82 interengages with the 'slot% of'the bolt holding bar86 for retaining the bolt in the compartment unlocked position until another coin is deposited toaagain start the cycle.

FroUn-Es 8 TO 1l'.--'MODIFICATION 1 Generally the lock mechanism of-this modification is provided with a lock barrel 171 movable only through a 90 arcand a separate key-operated means is utilized for 'controlling the opening of the compartment, the mechanism cover and the coin or check receptacles by an attendant. The check handling mechanism and the check-triggered, knob-controlled, lock barrel releasing mechanism of my preferred embodiment, disclosed in Figures l-7, are retained substantially unchanged.

This modification I of mylock mechanism is disclosed in Figures 8 through 11 and it will be understood, with reference to Figure 2, that the mechanism below the line XX in this figure will be utilized in the present modification.

Turning'now to Figures 8-11, the bolt holding bar releasing mechanism'includes a pivotally mounted camming member 175, manually. operated by a 'knob shaft (not shown) substantially identical-to the corresponding elements of my preferred embodiment. In order to reduce friction and the force required for operating the elements, I provided roller type cam followers 179 and 18l ,'located respectively on the free end of the cammi-ng member 175 and on the camming member holdingdetent It will be understood that the follower 179 coacts follower-181 coacts with a cam surface 182 carried by the 'lock'barrel l'iL'sh'o'wn in Figures 8 and 9.

As stated above, the lock bolt employed in this modification I is'rotatable only throughan arc of 90 and, therefore, cannot be operated by an attendant provided with a master key in the manner and for thefpurpose described intmy preferred embodiment. With the present device-the lock barrel releasing elements and the lock' mechanism cover 187 maybe actuated through separate key-operated means 188, carried "by the base plate'189 and located in the upperportion thereof.

It will be understood that the check handling elements, namely the slot and chute and the manually operated' lock barrel releasing mechanism, remain -s'ubstantially unchanged from that of the preefrred embodiment. The cover187 is provided with apertures 191 adapted to register and interengage with pins 193 carried-on the base plate 189, and obviously to effect mounting or removal the cover is giventhe necessary movement along the length of the'pins. The flange 197 is provided at its trailing end with anea'r portion 206 which, as shown in Figure 9, extends toward the base plate 189 and ends in a bearing surface having sliding'engagement with the base plate. The purpose of this extension is to coact with the base plate 189 and to space and to s'tabilize'the flange 197 should it become loose upon its mounting. Thus,

even though the flange should notbe rigidly carried: by the key-operated means 188 it would lie-spaced from the 'plate and guided so asto insure theoperation 'of'the holding bar 173'bythe 'arm 201;as presently described.

Toseeure andto :lock: the cover .187 =-on the basev plate 189 a horizontal stud 195 projects inwardly from the cover 187 transversely to the above mentioned pins 193, and coacts with a rotatable flange 197 carried by the key-operated means 188 for holding the cover 187 against movement lengthwise of the pins 193. In Figure 8 of the drawings, the pin and aperture arrangement has been shown only along the top edge of the cover, however, I may provide this arrangement along the lower edge of the cover if desired.

With the flange 197 in the position shown in Figure 8, the cover 187 is locked and held against movement longitudinally along the pins 193, and as shown in Figure 11, the flange 197 has been rotated to a position out of engagement with the stud 195 whereby the cover may be given movement longitudinally of the pins 193 for removing the same from the base plate 189.

To effect the release of the lock barrel 171 in this modification of my invention, the key operated means 188 carries a radially projecting arm 201 having a rounded cam surface 203 adapted to engage and depress the left end portion 204 of the holding bar 173. This movement of the holding bar 173 will be effected when the radially projecting arm 201 reaches the dotted line position, as viewed in Figure 8. If the key operated means 188 is rotated to the holding bar 173, engaging and operating position, the bar pivots about its mounting 199 elevating the opposite end 207 to disengage the slot 198 therein from the bolt 185 freeing the lock barrel 171 so that an attendant with a master key, similar to or the same as the customers key, may operate the mechanism and have access to the locker compartment 22.

Receptacles for receiving the proper and rejected checks have not been illustrated in the modification I of my invention, however, the usual receptacles employed for this purpose form no part of my invention and, therefore, are not shown or described.

Operation The operation by a customer of the mechanism shown and described as modification I is identical to that phase of the operation discussed in my preferred embodiment. After the articles to be stored have been placed into one of the locker compartments 20, a check of the proper size and denomination is deposited in the check guideway, actuating the selector detent 183, to free the knob-controlled lock barrel releasing mechanism, to allow movement of the lock bolt 185 to the compartment locked position wherein said bolt is in engagement with the compartment keeper 260.

A separate key-operated means 188 has been employed in this instance to allow an attendant to have access to the locker compartment, the lock mechanism and the check or coin compartment. This key-operated means 188 controls a flange 197 coacting with a horizontal stud 195 used for locking the cover 187 of my lock mechanism and a cam arm 201 utilized for disengaging the bolt holding bar 173 from the lock bolt 185. Then, by the use of a master key, similar to or the same as employed by the customer, the attendant may rotate the lock barrel 171 to the compartment unlocked position thus having access to the same.

The manner in which the attendant may have access to the lock mechanism and to the check receptacles by the separate key-operated means is thought to be obvious from the foregoing description.

FIGURES 12 to 15.-MODIFICATION II OF MY INVENTION This modification of my invention does not utilize the knob-controlled check release or knob-controlled lock barrel releasing elements employed in the preferred and first modified embodiments of my invention. Herein, the check, as it is pushed through the slot 226 and along the guideway 228 by the customer, contacts and partially operates the mechanism for releasing the lock barrel to allow movement of the same into the customers keyreleasing lock position. During the initial movement of the lock barrel by the customer, a cam member carried by the lock barrel operates in a manner presently described, to release the check and complete the lock barrel releasing operation.

Additionally this modification utilizes a lock barrel of the type employed in the preferred embodiment of my invention discussed above, wherein a master key effects movement of the same through a second arc permitting an attendant to have access to the locker compartment, the lock mechanism and the check receptacles.

With more particular reference to Figures 12-l5, the lock mechanism comprises the base plate 220 adapted to be removably mounted to the rear face of the compartment closure after the manner shown and described in connection with the above embodiments.

The mechanism is provided with a cover 222 hinged as shown at 224, and is provided with a check slot 226 and guideway 228 comprising a guideway associated with the base plate 220 which registers with a vertically disposed pivoted camming member 230 having a lower check actuated portion 232 and an upwardly extending cam section 234. The check slot 226 has associated therewith a spring arm 236, used to retain the check within the check guideway after said check, pushed by the customer, has initially operated the lock barrel releasing mechanism.

The camming member 230 is urged toward its normal inoperative position by means of a spring 238 and the lower check actuated portion 232 of this member is grooved as shown at 229 to receive the check deposited by the customer which, upon being pushed further into the slot, imparts movement to the camming member 230, initially positioning the same in the lock bolt releasing position, as shown in full lines in Figure 14.

The camming member 230 is held at this time in this intermediate position by means of a pivotally mounted spring pressed detent 240 carried by the bracket 242 on the base plate 220. At this time the camming member 230 has engaged the cam surface 244 of a pivoted bolt holding bar 246, loaded by the spring 247 and similar to that employed in the other embodiments of my invention. This movement of the bolt holding bar 246 in a counterclockwise direction, as viewed in Figure 12, completely releases the bolt 248 for movement into the dotted line position 248. A radially projecting cam 250 formed on a lock barrel 252 is adapted, during the first portion of the arcuate movement of the lock barrel, to coact with a pin type cam follower 254 carried by the cam section 234 of the camming member 230. This cam 250 will further swing the cam member 230 about its pivot into the phantom line position shown in Figure 14 causing the check actuated portion 232 to move away from the check to thereby permit the latter to drop down through the slot 226 and into the cover 222.

During the latter portion of the 90 arcuate movement of the bolt 248 and lock barrel 252, a second cam surface 262, also projecting radially from the lock barrel 252, engages a cam follower portion 264 of the detent 240 for freeing the camming member 230 allowing the same to return under the tension of the spring 238 to its original position. The holding bar 246 then returns to its normal holding position under tension of spring 247 against the limiting pin 263.

Now the compartment 20 will be locked and the customer may remove the key 258 and have sole access to the compartment with the exception of an attendant in possession of a master key. When the customer returns to the compartment and opens the same by use of his key 258, the bolt 248 will be rotated through its first mentioned arcuate path in a counterclockwise direction, as viewed in Figure 12. The bolt 248 is provided with a cam surface 266 whereby during the final portion of its movement the bolt holding bar 246 will be elevated, eventually snapping the slot 256 into engagement with 252 to the key-retaining unlock position, and it will be to modification in order to adapt it to different installa- -the bolt 248 for holding the same'iinl the customefis key-retaining unlock position, as showncby:gfull-glines in this Figure 12.

After the bolt 248 has been 'rotated'into its horizontal customers key-releasing, compartmentdocked position, an attendant, by use of a master key, may rotate the lock barrel 252 through a second 90 arc in a clockwise direction, as viewed in Figure 12. As the bolt assumes the dotted line position shown by numeral 248" in Figure 12, prior to the completion of movement through the second 90 arc, the compartment closure 22 will be unlocked. During continued rotation of the lock bolt 248 in a clockwise direction in the final portion of this second 96 movement, the same will engage alever arm 270 pivotally carried on the bracket 272, mounted on the base plate 226). As the bolt 248 engages and moves the lever arm 278, the same in turn will engage a spring pressed latch detent 272 efiecting release of the same from the keeper 2'74 opening the lock mechanism cover 222.

After the attendant has completed his inspection of the mechanism and removed the accumulated checks from the lower portion of the cover or other check receptacle, the lock barrei 252 must be returned through the are permitted by the master key, bringing the bolt into position in engagement with the compartment keeper 260. As the lock barrel 252 used in this modification of my invention will not release the master key unless the lock bolt 243 is in its horizontal position, removal of this key (not shown) from the unit will insurethe complete closing and latching of lock mechanism 222'as Well as the locking of the compartment 20 containing the customers stored articles.

From the foregoing description, the mode of operation of this second modification of my invention should be apparent. Briefly, upon the deposition of a suitablecheck in the check slot 225 and guideway 228, the lock barrel releasing mechanism is moved to and latched inan intermediate position wherein continued rotation of the lock barrel 252 by the customers key 258 through the first mentioned 90 are will effect further movement of the camming member 236) from this intermediate position to a position wherein the check actuated portion 232 is moved away from the check, permitting the same to drop down through the slot 226. Also, during this arcuate movement or the lock barrel 252 by the customers key 253, a cam surface 262 actuates the camming member holding detent 2%, disengaging the same from the camrning member 2363 allowing the same: to assume its original position to which it is urged by thisspring-238.

At this time, the lock barrel 252 is in its customers key-releasing lock position wherein the bolt 248 is in engagement with a keeper of the compartment 20 (not shown).

An attendant, at this time, by means of a master key (not shown) may rotate the lock barrel 252 through a second 90 arc to open the compartment and release, if desired, the cover 222 of my lock mechanism to have access to the lock elements or check receptacles.
